What is the sum of 12 – 5i and –3 + 4i?<br> –16 + 63i <br>9 – i <br>9 – 9i <br>15 – 9i
Svetach [21]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{9 - i}}}}}

Step-by-step explanation:

\sf{12 - 5i + ( - 3 + 4i)}

When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign of each term. That means, the expression remains the same. Just remove the parentheses

\longrightarrow{ \sf{12 - 5i - 3 + 4i}}

Collect like terms

\longrightarrow{ \sf{ 12 - 3 - 5i + 4i}}

Subtract 3 from 12

\longrightarrow{ \sf{9 - 5i + 4i}}

Collect like terms

\longrightarrow{ \sf{9 - i}}

Hope I helped!

Best regards! :D
